LT1460KCS3-2.5#TRPBF

Voltage Reference Overview

The LT1460KCS3-2.5#TRPBF is a micropower precision series voltage reference manufactured by Analog Devices Inc., housed in a 3-lead plastic SOT-23 package. It provides a nominal output voltage of 2.5V with an initial accuracy of ±0.5%. The device operates within a commercial temperature range of 0°C to 70°C and features a maximum temperature coefficient of 50ppm/°C. Key electrical specifications include a maximum supply current of 175µA, a minimum guaranteed output sourcing current of 20mA, and a minimum input-to-output differential voltage of 0.9V.

Voltage Reference Feature Summary

• Curvature compensation combined with trimmed thin-film resistors ensures high output accuracy and low drift across the operating temperature range.
• Capacitive load stability allows for fast settling times without requiring external output compensation capacitors.
• Reverse battery protection prevents current conduction and protects the device from damage during reverse polarity connections.

Voltage Reference Applications

• Handheld Instruments
• Precision Regulators
• A/D and D/A Converters

Voltage Reference Procurement Notes

Verify that the component matches the specified K-grade parametric tolerance (±0.5% accuracy) and commercial temperature range (0°C to 70°C). Confirm the SOT-23-3 package configuration and tape-and-reel delivery format align with assembly requirements. Ensure the ordering suffix #TRPBF corresponds to lead-free finish and RoHS compliance standards.

Voltage Reference Selection Notes

Select this part when a compact three-terminal solution is required for applications prioritizing low power consumption over ultra-high precision. The K-grade offers lower initial accuracy compared to A or B grades but maintains a stable 50ppm/°C drift profile suitable for general-purpose industrial environments where board space is constrained.
